Frequency Shift Keying Transmissions of an Image File Using GNU Radio, HackRF One, and the GR-Control Module

This project is an initial step in the construction of a satellite ground station at Howard University for the 3UCubed project which is a partnership between the University of New Hampshire, Sonoma State University, and Howard University to investigate the cause of unexpected drag of some low Earth-orbiting satellites. The problem addressed is whether a simple image file can be transferred between two HackRF One SDRs using GNU Radio and an open-source gr-control module using Frequency Shift Keying. The approach used incremental modifications of code supplied with the gr-control module. The project results indicate the file was transmitted and hardware and software may be used as the basis for exploring hardware and software for the Howard University ground station.
